Standing at the bottom of the bed, the cop pulled Carla down by her legs, as far as the restraints would allow before grabbing her hips, lifting and turning her over in one swift motion and smacking her ass hard. The younger woman's arms were twisted and uncomfortable but she didn't care, her breathing heavy as she waited desperately for the pleasure she knew the older woman would give her.
Thea took the dildo and covered it in lube, watching her wife attempt to grind against the bed, desperate for some more attention. She inserted the bulbous end inside herself and groaned loudly as it stretched her out. She forcefully spread Carla's legs wider, spanked both ass cheeks hard before kissing and sucking her firm skin, running her tongue from her ass all the way up her back, led on top of her making her feel the hard dildo between their bodies.
The cop took the remote control off the bed and turned it on the lowest setting, the vibrations filling her up, making her start to lose patience. She groaned and bit Carla's shoulder, enough to leave a mark but not break the skin and placed the remote in the younger woman's restrained left hand, placing her lips right next to her ear.
"That's the only thing you get to control. If you speak, you know what'll happen and if you scream, I won't stop, I'll just go faster. Understand?"
Carla turned her head, got eye contact with her wife and bit her bottom lip with a purely sexual expression before nodding at her.
The cop moved down her body just slightly, kissing and sucking on the soft skin of her back before lining the dildo up at her entrance. She went slowly, inserting the first couple of inches into her wife's wet pussy, listening to her moans and watching her fists clench. She pushed deeper despite Carla's tightness and didn't stop until she felt her wife's ass against her body. 
"Awww fuck babe!" The older woman said with her eyes closed, beginning to thrust back and forth slowly. Her arms either side of the younger woman's body taking her own weight, her end of the vibrator hitting her G-spot with every thrust.
When Carla increased the vibrations to medium, the cop took that as a sign she could go faster, the younger woman now fully accepting the length of the dildo with ease. She kissed her neck as her hips did all the work and before she knew it she was slamming into her pussy hard when her wife stopped moaning and started screaming loudly in her ear. She was fully trembling underneath her, her knuckles white as she firmly held the remote, biting the pillow as her lower body tried to meet the cops hard thrusts.
"Fuck! I'm gonna-" she realised what she'd done as soon as she heard her own voice. Her pussy clenched tight around the dildo but the cop removed it and spanked her repetitively over and over again until her ass turned pink.
Up on her knees, Thea forced Carla to do the same, her hands still restrained but her ass up in the air with the older woman right behind her. She lined up again but this time slammed hard into her pussy straight away then stopped, pulling out slowly then slamming back into her with just as much force. The cops pussy started to constrict, her orgasm was building as she forcefully used this woman she loved so much. Carla started to scream and despite Thea's building orgasm, she went faster as she'd promised.
Carla could hear her pussy being used, the dirty sound could just about be heard over her screams and it turned her on so much. She felt the cop gather a fist full of her long, wavy hair and force her head up, she could feel the moisture collecting between her legs, her pussy tightening around the dildo and she knew what was coming but she held on as long as she could. She wanted to feel the cop lose control against her so despite her desperate wanting, she flicked the remote control on to maximum.
The cops mouth watered, the vibrations tickling her G-spot when she lost all control. She let go of her hair and took a firm grip of Carla's hips with each hand and forced her body backward as she thrust forward as hard as she could, as quick as she could over and over again, the younger woman's screaming fuelling her desire. Carla shook wildly and then went limp, the cops firm hold being the only thing that now held her in position. The cop watched her wife's sex fluid sprinkling out onto the sheet underneath them, her own orgasm ripping through her body once she was sure Carla was fully satisfied. Her legs shook but she continued to thrust slowly with nowhere near as much force and collapsed on top of the younger woman, pushing her flat into the mattress.
